Teams around MLB will be wheeling and dealing over the next couple of weeks, but the clubs in the West divisions should be particularly active.

Not only are a number of contenders a piece or two away from roster completion and likely to make a trade, but there are also several organizations, such as the Padres and Giants, with valuable pieces to exchange for prospects.

Sporting News goes into great detail in breaking down trade scenarios and rumors for every team in the AL and NL West (teams in the buyers section are listed in order of talent level and World Series potential).

Los Angeles should easily win the NL West, but after falling short in the past two World Series, the organization’s sights are set far beyond regular-season success. A roster that could finish with the best record in the league, then, likely won’t be left alone. Closer Kenley Jansen is no longer a lockdown ninth-inning option (3.74 ERA), and the relievers behind him have been similarly inconsistent. The Dodgers will probably target one of several left-handed relievers on the market; Will Smith, Tony Watson and Felipe Vazquez are among the most frequently discussed options. The team may also look to transform what has been middling second base production into a legitimate strength. Last year, Los Angeles acquired Brian Dozier as a rental, and a move for an expiring contract such as Scooter Gennett potentially makes sense before the 2019 deadline. The Dodgers do have the highly regarded Lux hitting well in Triple-A, so perhaps they’ll decide to promote him rather than dealing assets for an external piece.

The Astros have no reason to trade top-10 prospects Forrest Whitley or Kyle Tucker given their strong playoff positioning and fairly complete roster. They might choose to deal from their next tier of minor leaguers, though, in order to secure back-of-the-rotation assistance. Someone like Marcus Stroman, or a pitcher on an even lower tier, like Jason Vargas, could represent the support they need behind Justin Verlander, Gerrit Cole and Wade Miley come the postseason.

The A’s have become clear buyers with their recent surge, but the front office is probably a year away from going all in. Almost everyone will be back next season, and it doesn’t make much sense to deal top-prospect pitchers AJ Puk or Jesus Luzardo at this point. Still, expect mid-sized deals from Oakland similar to the moves it made last year, when the team brought in a host of relievers led by Jeurys Familia as well as starter Mike Fiers. Already, the A's have traded for Homer Bailey. The decision now, on top of getting more quality relief pitching, is whether they make a move for one of the cost-controlled starters on the market. That choice to up the ante may come down to whether they’re able to acquire someone like Stroman or Madison Bumgarner without parting with Puk and/or Luzardo, a seemingly unlikely proposition given the strong market for those starters.

The Rangers are in the strange position of looking like a surprise contender while also perhaps being on the verge of collapse. They have one of the most barren farm systems of any of the competitive teams, followed closely by the Angels, so they won’t have much leverage unless they decide to deal Crouse and go for it this year. This has been a difficult team to judge; how it plays until the deadline will probably determine its plan of action.

It would be keeping with recent tradition for the Angels to deal uber-prospect Adell and prioritize the present despite an uncertain position in the standings (see the Dan Haren and Zack Greinke deadline deals). But if they want to get anyone of star or near-star value at the deadline, Adell would probably need to go given an iffy rest of their farm system. It would be a high-risk proposition that could come back to sting in a few years, but one that would also inject immediate confidence into the clubhouse, particularly if they can nab a high-profile starter.

Despite many outlets projecting the Diamondbacks to be sellers, that strategy doesn’t make much sense unless the group truly falls apart before July 31. With a winning record and close proximity to both wild-card positions, this surprisingly competitive team should get one more shot to compete before a larger teardown occurs after the campaign. Arizona doesn’t have an abundance of upper-minors talent to part with, so if it decides to be a buyer, it might be forced to stay away from the more popular names. That said, a few players could add significant energy to the squad without requiring a major trade package. Tigers outfielder Nicholas Castellanos, a good hitter with questions regarding his fielding, demanded a trade last offseason and is expected to be moved from Detroit eventually. He would be a nice stopgap for injured outfielder David Peralta. Elsewhere, Yasiel Puig would be a more exciting — but slightly more expensive — chip to plug into the outfield in Phoenix. Puig would be a rental, but he has been hitting at a high level of late and could conceivably flip the switch for the Diamondbacks down the stretch. Kevin Pillar is an option here, too. In terms of pitching, Arizona needs peripheral pieces rather than stars, specifically to help the back of its rotation and middle relief. Ian Kennedy, once a starter for the franchise, might make sense as a cheap reliever to pick up from the Royals. Kansas City would need to eat significant money, though, so Arizona’s attention could progress to simpler targets heading toward the deadline.

Trade deadline sellers in the West

Colorado Rockies

Valuable parts: None

Similar to the Diamondbacks, the middle-of-the-pack Rockies wouldn’t have much to lose by being buyers this season. Unlike Arizona, though, the Rockies are starting to nosedive. If Colorado is a couple of games under .500 at the deadline, then it would be surprising for the front office to add MLB players, though in that scenario, the organization will have a tough time acquiring meaningful prospects in sell mode given a roster bogged down by albatross contracts with early arbitration talents mixed in. The Rockies, then, are the West team most likely to stand pat this month.

As we wrote in mid-June, the Padres are on the cusp of being contenders but likely still a year away from playing in meaningful September games. By moving Yates and Stammen, who together should fetch at least one significant prospect, and one of their excess outfielders, San Diego can turn its immediate future into one of the most exciting in baseball. Get ready for the Padres to make the playoffs soon.

There’s no way the Giants are going to play themselves into the wild-card race in the nick of time, right? RIGHT?! Winners of five straight, they’re inching toward relevance in a crowded playoff field. For now, San Francisco is still likely to sell its top assets, which should rejuvenate a weak farm system. The current winning is simply a convenient piece of leverage for the front office to use against other teams, allowing it to act as though it doesn't truly need to give up Madison Bumgarner — that is, unless the winning streak keeps going until July 31, in which case the roster would improbably be kept intact.

Seattle Mariners

Valuable parts: 2B Dee Gordon, SS Tim Beckham, RP Roenis Elias

The Mariners have already dealt several MLB players this season, including a trade that sent Edwin Encarnacion to the Yankees. Expect the trend to continue this month, with the likes of Gordon, Beckham and Elias likely on the block. There probably won’t be any top-100 prospects coming back to Seattle, but even low-level lottery tickets are of use to the slumping franchise.
